FISHRENT; Bio-economic simulation and optimisation model

摘要: Key findings: The FISHRENT model is a major step forward in bio-economic model-ling, combining features that have not been fully integrated earlier models: 1- Incorporation of any number species (or stock) and/or fleets 2- Integration simulation and optimisation over period 25 years 3- effort TAC-driven management policies 4- Three independent relations for stock growth, production investments. feedbacks within the allow dynamic simulation. main application scenario analysis policy options. Complementary formulates complete set mathematical relations, but it also con-tains important assumptions, which remain to be tested empirically. Therefore presents challenging agenda empirical research, should lead further qualitative quantitative improvements in-dividual equations parameter values. Method: This was developed during EU-funded project 'Remuneration spawning biomass'. Its aim generate consistent sets scenarios an assessment potential resource rents different EU fisheries. comprises six modules, each focussing on aspect functioning fisheries system: biology (stocks), economy (costs, earnings profits), (TACs, access fees), behaviour (investments), prices (fish fuel) interface linking modules together.
